I've been using Sliccies for years, and I'm a big fan of the 0.3mm. I'm not a
huge multi-pen user, since I don't like barrels with a wide diameter. This
multi-pen has the narrowest barrel of any I've seen; about the same as an
average regular-sized pen.

The main complaint I've heard about the Slicci pens is the barrel width, so this
would correct that problem for people that feel the Sliccies have too narrow a
barrel. Personally, this is a bit wider than I'm used to but still great. It
also has the ridged grip I'm used to, which I love.

The refills are different than those in the single color Slicci pens, and maybe
I have bad luck but my blue is skipping a bit. The black and green are great.

Overall, a fantastic pen. I'm worried that the eight Sliccies I normally carry
may end up in a drawer, replaced by this one thin black beauty.
